Yes, all types of autocasting support all keys, I would tell you how to do it but itās not needed because in Grim Dawn all skills can have 2 keys bound to it so you can have both Q, Z and 1, 2 bound to your skills.
How do you know that? Is there some error? Do you have 32-bit processor? You donāt see the process working in Task Manager / Task bar? Thereās no confirmation when the program is working.
Periodic Casts support all keys right out of the gate. Something like this (but I still recommend 1, 2, 3, 4 because why not and they are easily recognizable by anyone and can be Secondary bindings
[periodic casts]
cast1=RButton:Q,W
delay1=50
initial_delay1=0
For the basic hold / toggle autocasting:
[9]
skill=Wind Devil
hold_keys=Space
[2]
skill=Aura
toggle_key=2
one needs to change the appropriate option in autocasting section (I always recommend newest version from GitHub)
From
[autocasting]
pressed_buttons=0,1,2,3,4,5,6,7,8,9
to for example
[autocasting]
pressed_buttons=Q,W
and then you can write something like this (Q, W buttons are automatically presses instead of 9 and 2)
[Q]
skill=Wind Devil
hold_keys=Space
[W]
skill=Aura
toggle_key=2
but I donāt recommend it because itās simply not needed as Iāve already explained
I recommend you telling me what functionality youād like and Iāll write you the best config for it.
